Attention is called by the AA. to the rarity of this histological feature of gastric tumor verified and described, on post mortem examination, in a white Brazilian male, 57 years old. The tumor is located on the lesser curvature of the stomach under the appearance of a crateriform formation, 3.5 cms. in diameter, fast adhering to the pancreas. The esophagus and cardia are not affected by this process. Metastases were found in the heart, liver, capsule of the pancreas, lungs and adrenal glands. The histological examination reveals in te primary tumor and in the metastatic foci a carcinoma of epidermoid type. The AA. are inclined to believe that the tumor might have arisen through an epidermoid-metaplastic process of the gastric mucosa.
